411sync is a service that allows you to make your rss feed available to mobile phone users. You can create keywords and assign your rss feed to them. When a user texts the keyword to the 411sync  phone number, she receives your feed as an sms message. On WAP enabled phones, users can enter keywords at wap.411Sync.com and receive your feed in their phone's browser. 411Sync also has an api for developers to use in creating mashups, including a photo api. This could be very useful as a way to add small bits of dynamic content to exhibits in museums. Simply put the 411Sync phone number and keyword on the exhibit label, with instructions. When the visitor texts the keyword to the number, she receives content you've created on a blog about the exhibit. Other applications might be to put the keyword and phone number on stickers, and then put them in public places. The keyword could link to the comment thread of a blog, as a simple way of creating an ongoing communal narrative or exploration of physical places. People could add to the comments at home on the web or via sms in situ.
